MACROS

MACROS:-
         Macros are used to perform the arithmetical operations. Macros can take up to 9 place holders. (&1, &2, -- - &9). If you want to maintain the same set of statements more than one location of the same program instead of this we maintain those statements in macro definition later we call the same macro definition from different locations of the same program.


Syntax of calling the macro: -
<macro name> <place holder1 value> <place holder 2 value>.

Note: - In macros definition should be the first and calling should be the next.
